The closest bit size you'll find is 1/32 (0.03125). The bit size you seek is not a standard, inch or metric. Unless you're working on the Space Shuttle, or something that requires such a tight tolerence, the cost of having one made wouldn't be justified.
Hold the bit in a Pin Vise and 'spin' it between your thumb and index finger. Pin Vises can be found in machine shop or automotive shop supply catalogs, I've seen them on a Snap-On tool truck before.
Hope this helps.[addsig]
